What is "heteromeles"

Heteromeles arbutifolia (; more commonly by Californian botanists), commonly known as toyon, is a common perennial shrub native to extreme southwest Oregon, California and Baja California. It is the sole species in the genus Heteromeles.

Toyon is a prominent component of the coastal sage scrub plant community, and is a part of drought-adapted chaparral and mixed oak woodland habitats. It is also known by the common names Christmas berry and California holly. Accordingly, "the abundance of this species in the hills above Los Angeles... gave rise to the name Hollywood."
